Freezing Rain Potential Monday Night through Wednesday Morning

The following statement was issued Sunday afternoon by the National Weather Service in San Angelo ....

...FREEZING RAIN POSSIBLE ACROSS PORTIONS OF WEST CENTRAL TEXAS
MONDAY NIGHT THROUGH WEDNESDAY...

A COLD FRONT IS EXPECTED TO PUSH SOUTH INTO THE REGION...USHERING IN
A SHALLOW COLD AIR MASS INTO PORTIONS OF TEXAS MONDAY AFTERNOON.
TEMPERATURES ARE EXPECTED TO DROP INTO THE 20S AND 30S LATE MONDAY
INTO TUESDAY MORNING ACROSS CENTRAL AND NORTHERN SECTIONS OF WEST
CENTRAL TEXAS.

AT THE SAME TIME...AN UPPER LEVEL TROUGH IS FORECAST TO DEVELOP ACROSS THE SOUTHWEST UNITED STATES...BRINGING INCREASED CHANCES FOR PRECIPITATION ACROSS WEST CENTRAL TEXAS MONDAY AFTERNOON THROUGH WEDNESDAY.

AS THE SHALLOW COLD AIR CONTINUES TO FILTER IN...WARMER...MOIST AIR WILL SURGE NORTH OVER THE COLD AIR...CAUSING ANY RAINFALL THAT DOES DEVELOP TO POSSIBLY FREEZE AS IT FALLS INTO THE COLD AIR NEAR THE SURFACE.
AT THIS TIME...THERE ARE STILL UNCERTAINTIES IN REGARD TO THE
LOCATION OF THE COLDEST AIR...AND THE AMOUNT OF MOISTURE AVAILABLE
TO PRODUCE PRECIPITATION. THE CURRENT FORECAST HAS THE SUBFREEZING
TEMPERATURES GENERALLY ALONG AND NORTH OF A SAN ANGELO TO
BROWNWOOD LINE TUESDAY MORNING...WITH TEMPERATURES IN THE MID 20S
ACROSS THE BIG COUNTRY...AND IN THE LOW 30S ACROSS THE CONCHO
VALLEY AND HEARTLAND.

AREA RESIDENTS SHOULD BE PREPARED FOR POSSIBLE TRAVEL HAZARDS
MONDAY NIGHT INTO WEDNESDAY ON AREA ROADS...ESPECIALLY ON BRIDGES AND
OVERPASSES. STAY TUNED TO NOAA WEATHER RADIO...LOCAL MEDIA...AND
INTERNET SOURCES FOR THE LATEST FORECASTS.
